I totally agree with Ron about Wusthof knives. The Wusthof Culinar Cooks Knives are forged from one piece of chromium-molybdenum steel, like Ron said has a high carbon content.
If possible and budget permitting your better off going for one piece knives as they are better balanced. This may not be much of a problem for home cooking, but makes it easier if you are using them a lot in a busy kitchen.
You should be able to get a basic 16cm blade for around £60.00 which is fairly reasonable. When you get up to the large meat range blades they can become very expensive. I have seen them in excess of £250.00 each.
You know what they say, if you want quality you have o expect to pay for it. Good thing with these knives is they can be bought on their own, a bit like a mechanic buying Snap On tools. See I do know about something other thn cooking!
